Low-salinity groundwater reserves beneath the sea bottom and submarine groundwater discharges (SGD)are of great importance in the use and management of coastal water resource. A preliminary hydro- morphogeologic analysis allows for considering the presence of low-salinity groundwater in the offshore of the Laizhou Bay (Southern Bohai Sea, China). In order to detect the potential SGD the analysis of the Sea Surface Temperature (SST) anomalies has been carried out by Landsat images in the seasons when seawater and groundwater are characterised by the largest difference in temperature. The main outcomes of the study are the following. At the nearshore scale, along the intertidal zone of the Southern bay, where the unconfined aquifer discharges, patchy cold water anomalies occur,approximately in the same positions in different tide conditions. At the embayment scale in the Eastern Laizhou Bay where the confined aquifer is likely exposed, cold water anomalies are spread out.
